Scramjet? Well, if you had plans of a small scramjet, I think you'd have CIA, DHS, NHS, FBI, KGB and a dozen assorted other members of the alphabet soup at your place in no time at all. Not to mention black helicopters and Men in Black.

But, suppose you had such plans, what on Earth would you do with them? Build the thing?

You obviously did not get my last posting.

Do an Internet search on 'scramjet' and you'll find out how likely it is for anyone to have such plans.

Two (2) scramjets have been successfully tested in the known history of aerospace. One in the US and another in Australia. Both have cost more than you and your family and all your friends put together are likely to earn in your entire lifetime. The thing doesn't even begin to work properly before it flies at several times Mach speed.

Now please, why do you hope to get a plan of such an engine? If you did get it by some fantastic chance, what the hell would you do with it? Build it? Do you have a spare SR 71 in your garage that you can use for testing, or what?

Well, friend, believe it or not, but as I'm writing this, I am raising a glas of Casal Garcia vinho verde to you. I wish you luck.

Information on anything relating to these engines is very difficult to find anywhere but in this forum. Furtunately, there are plentry of good people here ready and willing to help with information and advice.
